Abstract: PURPOSE:To provide a light guiding plate which is thin and in which the luminance in the light-emitting surface is even, and when it is used as a back light, the need for increasing the number of light-diffusive sheets can be dispensed with by arranging the dots consisting of a light scattering and transmitting substance and/or a light diffusing and reflecting substance so that the center distances between the two dots out of arbitrary adjacent three dots are equal. CONSTITUTION:In a light guiding plate which is made of a light-transmitting material and on the wider surface of which on the one side a light scattering and transmitting substance and/or a light diffusing and reflecting substance has been coated in a dotted state, dots are arranged in such a way that the distances between the centers of the two dots out of arbitrary three dots being adjacent are equal. The material of the light guiding plate will do, if it is a material that efficiently transmits light, for example, quartz, glass, light transmitting natural or synthetic resins such as acrylic resin. As the light scattering and transmitting substance and/or the light-diffusing and reflecting substance, silica, barium sulfate, or the like are used. Assuming that, for instance, hexagonal lattices are laid on a plane, the dot pattern is arranged in such a way that the center of the hexagonal lattice is the center of the dot (light scattering and transmitting substance and/or light diffusing reflecting substance).

Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To protect a transparent electrode and to prevent an erroneous operation of an IC by light by a method in which a pigment, with which a light is absorbed and diffused to a coated protective film, is applied to the transparent electrode. SOLUTION: A transparent electrode is formed on a glass substrate 1 in a liquid crystal indication device, liquid crystal indication glass 2 and an IC 3 are mounted, and the transparent electrode and the IC 3 are covered by a protective film 4. The protective film 4 is formed by applying a frigment, having light absorbing function to resin material and having light reflection/scattering function to the transparent electrode on the substrate 1 and the IC 3. Accordingly, as it is unnecessary to protect using a part dedicated to it, the increase in cost of part and the increase in manhours can be prevented, and also as the close adhesion between the IC and the protective film is excellent, the effect of light shielding is high, and the operation of a liquid indication device can be stabilized.

Abstract: PURPOSE: To obtain an inverter device which can absorb a change in a power- supply voltage or a difference in a rated voltage by installing a voltage control function which makes the output voltage of an inverter a constant value in a value designated so as to correspond to its output frequency with reference to a change in an AC input voltage. CONSTITUTION: When an operating frequency is designated by a frequency instruction signal SF, an optimum voltage used to drive a motor 4 is read out as a target output voltage from data which is stored in an internal ROM for a CPU. Then, the estimated voltage of a voltage VIN corresponding to a detection signal SVIN is read out as an estimated input voltage from input-voltage- detection data which is stored in the internal ROM for the CPU. The ratio of the read-out target output voltage to the estimated input voltage is operated by the CPU. A change in the input voltage VIN for an inverter apparatus is estimated as a voltage ratio 'target output voltage/estimated input voltage], and an output voltage VOUT can be maintained at a target voltage with reference to the change in the input voltage VIN.
